Plugin Name -- WordPress 插件

This is pretty straight forward plugin that takes your locally infor- mation and produces a set of sunrise, sunset and twilight data.
You need to know how many hours your time zone is from Greenwich Mean Time. There is a feature for selecting Daylight Savings Time (DST), but this must be done manually when your location makes the shift. Because of different DST practices and occassional changes made by the governments, I did not try to code DST changes. This can be found at many time zone sites, like http://www.worldtimezone.com/ and http://www.time.gov.
Also, you have to be able to input your decimal degrees latitude and long- itude. Google Earth can be set up to get this.
I am using this widget on my own blog and intend to for the long-term. So, I think it is reasonably safe. There is very little error trapping for entering the wrong values in the admin window on the widgets page. If you have issues with the plugin, or ideas for improvements, please let me know.

stu-in-flag@stu-in-flag.net. I'll see what I can do.

Upload the unzipped folder and contents to the /wp-content/plugins/ directory
Activate the plugin through the 'Plugins' menu in WordPress
Include the widget on your sidebar, header or footer as allowed by your theme. This is done on the 'Widgets' admin page which is found in the 'Appearance' section of the admin menu. See screenshot2.png. Drag the widget to the appro- priate section.
Setup the widget to show your picture using the admin window. Your latitude and longitude need to be in decimal degree format. You can find this on many map websites. Google Earth works well for this. The time zone is set with GMT time zone difference. This can be found at many time zone sites, like http://www.worldtimezone.com/ and http://www.time.gov.
Very important: DAYIGHT SAVINGS TIME MUST MANUALLY CHANGED. With differences around the world, and local law changes, it's would be craziness to try and code these. So, when you spring-forward or fall-back, change the Daylight Savings Time checkbox. Lucky for me, I live in Arizona where we don't mess with the time.
